It is natural for everyone to experience it sometimes, but it is essential to know the synonyms for the term and take appropriate steps to overcome it. Some of the synonyms for the phrase "become unproductive" include slump, stagnate, idle, languish, wither, and flounder. When someone slumps, they become unproductive due to a decrease in motivation, or when they stagnate, they stop making progress. On the other hand, idleness speaks of being inactive or lazy. To overcome these stages, stay active, motivated, and take proactive measures to remain productive.
